Abstract: The production of electric energy requires energ y investments not only for direct fuel input but for the construction of power plants and for the extraction of primary energy fuels as well. When the overall energy balance of energy convertinq systems has to be assessed these energetic investments misst be included. In the present investigation the overall energy input of different nuclear power plant typen (comprising the nuclear fuel cycle) is computed and compared with a coal-fired plant. Moreover a time-dependent energy balance for the expansion of nuclear capacity according to the existing nuclear programs is calculated. Even applying only Light Water Reactors the nuclear expansion program (with an installed capacity of 50 GW$_{el}$ in 1985 and 170 GW$_{el}$ in 2000) would result in anaccumulated fossil fuel saving of approximately the tenfold amount of primary energy consumed in the Federal Republic of Germany yearly today.
